To ullzwhom it mag concern:

Be it known that I, ANDREW State of California, have invented certain new and useful Improvements. in Vehicle. Wheels, of which the following is a specification. i ;f 7

This invention relates to improvements in resilient vehicle wheels with special reference to :1 wheel for automobile trucks.

The p'rincipal object of .my invention is to provide a strong rugged wheel'having retruck wheels, at the same time providing a tread which is cheap torenew and WhlCl] provides an antiskid surface:

With these and other objects view myinvention consists in the new and novel con struction and arrangement of partsas here-' in described and illustrated in the accompanying drawings and as more particularly pointed out in the annexed claims.

For a full comprehension; of the device reference should be had-to the attached Figure 1 is a view'qn side elevation ofthe.

improved wheel .with a portion broken away to show the resilient supporting means. Fig. 2 is a top plan view of the same showthe tread supporting members. Fig. 5 is a top plan view of the same. Fig. 6 1s a longitudinal view in section through the resili ent supporting means. Fig. 7 is a fragmentary sectional view on 77 Fig. 1.

Denoting corresponding parts by the same numerals of reference in the several views, the central portion of this'wheel is composed of two similar portions each consisting of acentral hub 1 into which is cast a disk 2 having the radial corrugations 3. On the outside periphery of' this disk is cast an annular rim 40f L section; this rimand the hub being finished and held together by bolts 5 and 6, the latter of which is provided with a spacing sleeve 7 Intermediate the length of the corrugations are otherbolts- 8 which arealso provided. with spacing sleeves. a 1 v The hub members 11am provided with radial extending finger-s 9 'on the periphery of which is supported a .10 having This screw issprov-ided .withahead 12 hav'-- in adisk -14. This disk-is 'provlded with an annular. upturned flange 15- providing'aseat for the resilient material .16. .While I have a threaded holes forthe' adjusting screws 11.- VV. LIVING-1 v ing a conical-.or'ball shaped point 131thereon which fits withina similarlyshapedsocket 14:

' shown this as ,acylindrical block of soft-l 5 rubber any other resilient means may bev used. similarly shaped disk 17 is pro.-

-vided on the opposite end .of this block which is provided with a cylindrical socket i 18. Supported} on adjacent disks is" the irregularly shaped tread carrying member denoted in general 'by 20 coniposed. of two: integral substantially; rectangular hollow frames" 21 and 2 2" in' staggered relation-10* These members are curved to on the under' side with a longitudinal rib 23-having a-width -e'qua l to'the spacin be-f' tween the members '4. I Onv each end; 0 this. rib is a cylindrical-lug 24; half: the width thereof and adaptedto-"res't in the Y socket,

. the lugs being oppositely. disposed stcli1 that tjtoge erin the lugs of ad acent members the same socket-18.- At the 'center'ofthe rib,

compression of resilient means 16.

blocks 26 which-LI prefer to make'of wood b is a slot 25 which fits over the sleeve thereby limiting the outward movement oi -20 "by the Inthe' hollow ,frames21 and 22 arebolted tion. These blocks are held" bolts:v 27;

passing through both frames so'that they may be easily renewed.

In assembling the ring 10 is placed over 1 I the finger 9 ofir'one central disk the other half then; bolted in place- The mem 20 are then forced in positiongs'o as to. give the resilient means 16 an initialcompression and held by bolts 6, the amount 'of com--' pression being-regulated by screws 11.. In} use as the wheel rolls along the ground the lower. blocks .16 are compressed, the upper 1 0- ones extended and the side ones are slightly flexed. The compressionatthe bottom of the wheel causes the inwardmovementof members. 20. and a slight rolling n ovement of Iugs-24Linthe. sockets 1-8.

By placing the blocks26 in: staggered re} lation a substantially cylindrical surface is obtained and .the weight d1str1butedover agreaterfnumbe'r ofblocks 16.

" While 'I ihavefshown" the prete ded-"he" i scribed comprising,

bodiment of the invention it will of course be understood that changes may be made in design anddetails of construction Without depfiting from the spirit thereof and that I claim such modifications as are included Within the scope of the attachedclaims. I atl claim is I 1! A vehicle Wheel of the character dea hub, radial resilient members carried by said hub, sockets on the outer ends of sai'dmembers, suitably supported" annular rims, having-a channel therebetween, a plurality of circumferentially disposed tread carrying members held in said channel and supported in sockets of said resilient members, said tread carrying members being formed of two parallel rectangular frames and a central supporting rib, said frames being; in staggered relation and provided with means for securing tread blocks therein.

2. A vehicle Wheel of the character described comprising, a hub, radially corrugate disks cast therein, annular rims cast on the periphery ofsaid disks, spacing bars he means ping relation with a lug of the adjacent a member, said overlapping lugs being supported in socket of resilient member, slot in said rib adapted to retain the said mem her on the said spacing bars, substantially rectangular staggered frames formed on said tread members and tread blocks bolted in said frames substantially as and for the purpose described.

lln testimony whereof ll affix my signa ture in presence of two Witnesses.
